BACKGROUND

This application claims priority to U.S. Provisional Application Ser.No. 61/759,104, filed Jan. 31, 2013, entitled “Snow Plow Cutting Edge.”

Snow plows can be mounted on a vehicle and used for removing snow,debris and ice from outdoor travel surfaces, such as roads, driveways,and walkways. A snow plow blade typically comprises contoured, and/orwedged plow surfaces, the bottom of which may rest upon the targetsurface during plowing, or a cutting edge attached to the bottom of theplow blade. Often, snow plow cutting edges are affixed to the bottom ofthe plow blade to provide a more desirable snow/ice removal edge, and/orprovide a wearable surface that can be ready removed and replaced asneeded, instead of replacing or repairing a damaged plow blade.Commonly, plow cutting edges are comprised of metal (e.g., steel),rubber, polyurethane or combinations thereof.

FIG. 1 is a component diagram illustrating a side perspective view of anembodiment of an exemplary cutting edge 100. The exemplary cutting edge100 comprises a front surface 102 and a rear surface 104. In thisembodiment, the front surface 102 is configured at a desired front angleto vertical, for example, where the desired front angle comprises anangle appropriate for snow and ice removal when engaged with a snow plow150, such as between ninety and forty-five degrees from vertical (e.g.,acute to the target surface).

In this embodiment of the exemplary cutting edge 100, the rear surface104 comprises a first rear portion 108 and a second rear portion 110.The first rear portion 108 is configured to be at a desired rear angle,for example, where the desired rear angle of the second rear portion 110comprises an angle that allows the rear surface 104 to be disposedadjacent to, and in contact with, a bottom portion 152 of the snow plow150, when engaged with the snow plow 150. The second rear portion 110defines a bottom extension 112. The bottom extension 112 comprises arear top surface 114 configured to be relatively parallel to a targetsurface 158 (e.g., pavement) when the exemplary cutting edge 100 isengaged with the snow plow 150. The bottom extension 112 furthercomprises a rear face surface 116 configured to be relativelyperpendicular to a target surface 158 (e.g., roadway) when the exemplarycutting edge 100 is engaged with the snow plow 150.

Further, in this embodiment of the exemplary cutting edge 100, theextension 112 extends rearward from the front surface 102 to a desiredlength, where the desired length, for example, allows the rear facesurface 116 to be disposed at a position rearward of the bottom portion152 of the snow plow 150, when the exemplary cutting edge 100 is engagedwith the snow plow 150. As one example, the disposition of the rear facesurface 116 on the extension 112 at the position rearward of the bottomportion 152 may allow the snow plow 150 to be effectively used for backdragging (e.g., pushing or moving snow and/or ice in a rearwarddirection with the plow).

This embodiment of the exemplary cutting edge 100 comprises a bottomsurface 118 configured to be disposed relatively parallel to a targetsurface 158 when the exemplary cutting edge 100 is engaged with the snowplow 150.
